PARIS (Reuters) - Roger Federer's dream return to the French Open continued as the Swiss waltzed into quarter-finals by giving Argentine Leonardo Mayer a 6-2 6-3 6-3 masterclass on Sunday.

The 20-time Grand Slam champion, back at Roland Garros after a three-year hiatus, edged closer to a potential semi-final showdown with champion Rafael Nadal by cruising through the opening rounds seemingly unchallenged and his last-16 encounter was no exception.
